Directions: 

• Thoroughly clean and dry surface from oil, dirt and grease with Mineral Turpentine firstly and then Methylated Spirits. Allow to dry completely before applying silicone. If there old silicone which needs to be removed, we recommend using SELLEYS SILICONE REMOVER, this ingenous product makes removing old silicone easy.
• We also recommend sanding the surface back with a good quality sanding block, such as a ROTA COTASanding Block Medium/Course grain, as the silicone will adhere more readily to a scratched up surface.
• Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
• Cut the seal at the top of the cartridge and cut the nozzle at a 45° angle, to the size of the gap opening. Fit the nozzle to the top of the cartridge.
• Insert the cartridge into a caulking gun such as SELLEYS LIGHT SPEED Caulking gun. We recommend SELLEYS LIGHT SPEED Caulking Gun, as its new innovative pressure release design reduces the mess which results from run on and stress on your hands, which is critical if you are doing a lot of sealing.
• Hold the caulking gun at a 45° angle. Press the nozzle opening against the joint, apply steady pressure to the caulking gun and extrude the silicone sealant forcing the sealant into the gap and move in a pushing motion, along the joint in one smooth action.
• For a smooth finish, smooth with a finger dipped in mineral turpetine or for a professional finish use a paint scraper such as a 50mm ROTA COTA Soft Grip Scraper dipped in mineral turpetine.
• Excess sealant must be cleaned up before the sealant skins in 5-10 minutes. Wipe excess away with a cloth dampened in mineral turpetine or use a SELLEYS Hand Kleen Wipe. Remove tape before the sealant skins. Clean tools immediately in mineral turpetine.
• Avoid smearing on surrounding surfaces, see handy tip.
• Sealant will cure fully in 72 hours. As this point any unwanted sealant can be removed by trimming with a sharp blade, but avoid under cutting the seal.

Application Tips: 

• Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
• When first applying product, extrude a small amount onto a piece of scrap material to ensure a smooth continuous flow of silicone sealant.
• Remove the tape before the silicone sealant skins.
• For a better finish complete painting prior to use of the sealant as it can not be painted over.
• For a better finish use a spatula dipped in mineral turpetine or detergent and water to tool off the sealant.
• Work in sections that can be completed before sealant skins. Tooling off and tape removal must be completed before skinning occurs or a rough surface, may result so working in sections allows for a better finish.
• Keep a pack of SELLEYS Hand Kleen Wipes handy to wipe up any spills and for cleaning any material off the skin before it cures. They are an easy and effective way to keep clean on the job.

• Uncured product may irritate eyes. If in eyes, flood the eyes for at least 15 minutes and seek medical advice.
